...fourth pic showing some of the chips while chambering; fifth pic shows a re-sized 9mm shell in the new chamber; sixth pic is what we have now...
The rear sight base has been contoured at rear; rear sight base is ~1/10" longer than Luger because I'll be using a shortened Mauser C96 tangent rear sight. Front sight dovetail is 5/16"; smallest I could find, which means my front sight will be fabricated in place. Muzzle and breech have been turned down slightly. Breech (where thread is) is still about 1/8" longer than needed, and thread diameter is still a bit oversize. Chamber will be cut deeper and headspace reamed in when breech is cut to length and barrel is fit to receiver.
I'll start on the front sight blank and rear sight base next.
